Engine stops under load

Engine starts at idle but stops under load is a common problem indicating lack of torque. Let's look at the reasons.

Main reasons

1. Overload.The moment of resistance exceeds the capabilities of the motor.
2. Phase loss.In two phases, the motor does not pull the load.
3. Low voltage.The torque drops in proportion to the square of the voltage.
4. Breakage of the rotor rods.The motor is weak under load, hums.
5. Slippageof the coupling or belt (mechanical cause).

How to find the cause

> Load voltage make sure that the load itself is not jammed or increased. Then check the voltage and all three phases. If external causes are excluded, but the engine still stalls, a break in the rotor rods or an interturn short circuit is likely, which is detected by diagnostics. Eliminated by repair of an asynchronous motor.
